The value structure of Medieval Art is mid-key: quiet, controlled, and cohesive. Yellow, ochre, sienna: warm hues deployed as the palette's primary energy. Saturation is measured and controlled, giving the palette presence without visual aggression. The most saturated colour, #E9D181, is reserved to 8.1% of the surface, where it acts as a focal punctuation. At 61 units of value range, the palette has the tonal breadth to sustain complex spatial readings.
